Chapter 3 Connective Tissues

matrix

connective tissues cells are usually some distance apart, and they have a considerable amount of intercellular material between them

connective tissues

connect, support, protect, provide framework, fill spaces, stores fat and produces blood cells

loose connective tissue

1. Binds organs together, and holds tissue fluids

2. Located beneath the skin, between muscles and beneath most epithelial layers

Adipose tissue

1. Functions include protection, heat insulator, storage of fat, and serves as a cushion for joints, as well as, organs.

2. Located beneath the skin, around the kidneys, behind the eyeballs, and on the surface of the heart

3. The amount of adipose tissue in the human body is usually related to a person’s diet. If a person over eats excess food substances they are likely to be converted to fat and stored in it

Fibrous connective tissue

1. this tissue is composed of largely of strong collagenous fibers

2. It is found in the tendons, ligaments, eyes, and skin

3. It’s function is to bind organs together

Tendons

connect muscles to bones

ligaments

connect bones to bones

Cartilage

1. Provides support and a framework for various parts

2. lacks a direct supply and is slow to heal following and injury

Hyaline cartilage

located at the ends of bones, nose and rings in the walls of respiratory passages

Elastic cartilage

Framework of the external ear and part of the larynx

Fibrocartilage

located between the bony parts of the backbone and knee

Bone

1. Is the most rigid of the connective tissues.

mineral salt and collagen

The intercellular matrix of bone contains

blood

1. composed of red cells, white cells, and platelets suspended in plasma.

2. blood cells are formed by special tissues in the hollow parts of certain bones

connective tissue, epithelial, muscles, nervous

four types of tissue
